Multi-Format Codec Engines #120

Closed quamt closed 1 year ago

quamt commented 1 year ago

Hello @rigaya ,

I want to check.

On the intel webpage for the A770 https://www.intel.sg/content/www/xa/en/products/sku/229151/intel-arc-a770-graphics-16gb/specifications.html it says Multi-Format Codec Engines 2

Multi-Format Codec Engines
Multi-Format Codec Engines provide hardware encoding and decoding for amazing video playback, content creation, and streaming usages.

Does that mean it can run two encodes at the same time without affecting the other engine? I didn't see the 2 engines in the features check. Or did I misunderstand?

I didn't see the 2 engines in the features check.

Feature check is checking per device (GPU), and not per engine.

With Arc A380 which also shown to have 2 engines, I can get half the throughput per process when running 2 process at the same time.(total throughput is the same.)

It might be that oneVPL API automatically use 2 engines, but not sure about that, there is no way to check.

Ok. Thank you.
